摘要： One of the routes to prepare optically active 2-(4-aryloxyphenoxy)propionic acid ester herbicide is to couple optically active 2-(4-hydrophenoxy)propionic acid esters with halogenated aromatic or heteroaromatic compounds. Conversion of the optically active 2-(4-hydroxyphenoxy)propionic acid ester into the acid salt prior to the coupling step effectively prevents the racemization that unexpectedly occurs otherwise.

摘要： Reduced calorie food compositions are produced by replacing at least a portion of the fat content of a conventional food with an improved low calorie edible oil substitute that does not cause anal leakage. This substitute is an oil-like polymer fatty acid ester having the property of being substantially hydrolyzed during the process of intestinal digestion into a mixture of fatty acids and a non-caloric water-soluble or water-dispersible polymeric alcohol. This digestive mixture is in a non-laxative, non-oily physical state, and thereby avoids the problem of anal leakage common to oils with limited digestibility. Of particular use in this invention have been fatty acid esters of water-soluble polyoxyalkylenes.
摘要翻译：通过用不会引起肛门泄漏的改进的低热量食用油替代物代替常规食物的至少一部分脂肪含量来制备减少热量的食物组合物。这种替代物是一种油状聚合物脂肪酸酯，其具有在肠消化过程中基本上水解成脂肪酸和非热量水溶性或水分散性聚合物醇的混合物的性质。这种消化混合物处于非泻药，非油性物理状态，从而避免了消化率有限的油常见的肛门泄漏问题。在本发明中特别有用的是水溶性聚氧化烯的脂肪酸酯。
